Finally, a systematic framework of improvement measures was provided for Chinese MET. A brief review of the increasing demand on seafarers for energy efficient ship operation was carried out from four aspects including regulations, practices on board ships, alternative fuel and renewable energy sources. Based on the increasing demand, the barriers existing in the Chinese MET was …

Is Public Transit's 'Green' Reputation Deserved?, Justin Beaudoin

PSU Transportation Seminars

While public transit has a reputation as a potential means to ameliorate the adverse environmental effects of automobile travel, there have been very few empirical studies of the marginal effect of transit supply on air quality. We explore whether any of the substantial improvement in air quality observed in the U.S. from 1991 to 2011 can be attributed to increased public transit supply by developing an equilibrium model of transit and automobile travel volumes as a function of the level of transit supplied. We then empirically analyze the effects of the level of transit supply on observed ambient pollution levels …

Where Do Riders Park Dockless, Shared Electric Scooters? Findings From San Jose, California, Kevin Fang, Asha Weinstein Agrawal, Jeremy Steele, John Joseph Hunter, Ashley M. Hooper

Mineta Transportation Institute Publications

Dockless, shared, electric kick-scooters started popping up on U.S. city streets without warning in 2017. Reaction to the shared scooters came swiftly and strongly. On the one hand, the scooters have proven popular with riders, attracting investment capital and expanding service to additional cities. But others have been less enthusiastic, with a central complaint being how shared scooters are parked.

This perspective explores the extent to which parked shared scooters pose a problem to others on streets, sidewalks, and public spaces, using empirical evidence documenting where scooters have been parked in downtown San Jose, California.

Not Just An Ache: Examining The Rate Of Musculoskeletal Pain In City Bus Drivers, Jeremy Steele

Mineta Transportation Institute Publications

This paper examines the rates of musculoskeletal discomfort in a sample of 957 city bus drivers at King County Metro, a public transportation agency serving the greater Seattle area. It also examines how often such pain prevented drivers from doing their normal work, needed treatment from a medical professional, or incited one or more worker’s compensation claims. To assess the level of musculoskeletal discomfort in city bus drivers, an anonymous survey was distributed to drivers at King County Metro, a public transportation agency serving the greater Seattle area. This survey consisted of a Nordic Questionnaire asking drivers whether or not …

Transportation Behavior Change...Now With Science!, Jessica Roberts

PSU Transportation Seminars

How can we encourage people to make use of the transportation systems in place - to improve transit ridership and, in turn, to improve the health and happiness of our societies?

New findings in behavioral science could unlock new, more effective ways to change transportation behavior...but only if we have a way to find and use that evidence. TransLink (Vancouver BC) undertook a groundbreaking research effort to use cognitive biases to explain why people drive today, and and to identify possible "nudge" strategies to shift those trips to transit and active modes. The resulting report includes brand-new ideas that area …

Does Length Of Ride, Gender Or Nationality Affect Willingness To Ride In A Driverless Ambulance?, Stephen Rice, Scott R. Winter, Rian Mehta, Joseph R. Keebler, Bradley S. Baugh, Emily C. Anania, Mattie N. Milner

Publications

Due to the frequent lack of ambulances and personnel, the purpose of this study was to examine consumers’ willingness-to-ride in an ambulance that was either driven by a human driver or completely automated (with no human driver) based on the gender of the participant and their nationality, either Indian or American. A two-study experimental design was utilized using over 1,000 participants. In Study 1, the length of the ride and the type of driver were manipulated while in Study 2, the length of the ride was manipulated across genders and nationality. Study 2 also collected affect measures to complete a …

A Study Of Public Seaport Governance In The United States, Christopher Michael Williams

School of Public Service Theses & Dissertations

Seaports are important economic engines serving many metropolitan areas in the United States. Most seaports in the U.S. are public-owned and managed by a set of elected or politically appointed board members. Indeed, this is public governance in action but the field of port governance seems to be focused on the study of operating efficiencies and less concerned with the public governance aspects of seaports.

The term “governance” in a public organization conveys a level of democratic accountability to the citizenry for management of public-owned resources but, until now, studies of seaport governance in the U.S. have not focused on …

The Future Of California Transportation Revenue, Martin Wachs, Hannah King, Asha Weinstein Agrawal

Mineta Transportation Institute Publications

Stable, predictable, and adequate transportation revenues are needed if California is to plan and deliver an excellent transportation system. This report provides a brief history of transportation revenue policies and potential futures in California. It then presents projections of transportation revenue under the recently enacted Senate Bill 1, the Road Repair and Accountability Act of 2017. Those revenue projections are compared with projections of revenue should SB 1 be repealed by voters in the November 2018 election. State-generated transportation revenues will be higher under SB1 than if the act is repealed. For 2020, the mean projection is that the state …

Examining The Development Effects Of Modern-Era Streetcars: An Assessment Of Portland And Seattle, Jeffrey Brown, Joel Mendez

Mineta Transportation Institute Publications

Most U.S. cities pursuing streetcars are doing so primarily for their purported development effects, as opposed to for their transportation role, yet there is little evidence about the nature or magnitude of these development effects due to a scarcity of rigorous, empirical research. Most available work simply presents descriptive information about development outcomes (typically measured as changes in population, employment, land values, or permit activity) within streetcar corridors as indicators of the streetcar’s development effects. Alternate factors which may have influenced such results are often not considered, placing into question the validity of such measures.

This study examines the development …

Segment: Applicability Of An Existing Segmentation Technique To Tdm Social Marketing Campaigns In The United States, Philip L. Winters, Amy Lester, Minh Pham

TREC Final Reports

Social marketing seeks to develop and integrate marketing concepts with other approaches to influence behaviors that benefit individuals and communities for the greater social good. Social marketing is a useful transportation demand management (TDM) planning approach to promote travel-behavior change. The purpose of this study was to explore a consumer market segmentation technique (SEGMENT) successfully used in Europe for its applicability to social marketing campaigns in the United States. Major contributions of this project are the validation of a successful existing segmentation technique for applicability in the United States, which will maximize the impact of TDM social marketing campaigns on …

Traffic-Cascade: Mining And Visualizing Lifecycles Of Traffic Congestion Events Using Public Bus Trajectories, Agus Trisnajaya Kwee, Meng-Fen Chiang, Philips Kokoh Prasetyo, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

As road transportation supports both economic and social activities in developed cities, it is important to maintain smooth traffic on all highways and local roads. Whenever possible, traffic congestions should be detected early and resolved quickly. While existing traffic monitoring dashboard systems have been put in place in many cities, these systems require high-cost vehicle speed monitoring instruments and detect traffic congestion as independent events. There is a lack of low-cost dashboards to inspect and analyze the lifecycle of traffic congestion which is critical in assessing the overall impact of congestion, determining the possible the source(s) of congestion and its …

Inferring Trip Occupancies In The Rise Of Ride-Hailing Services, Meng-Fen Chiang, Ee-Peng Lim, Wang-Chien Lee, Tuan-Anh Hoang

Research Collection School Of Computing and Information Systems

The knowledge of all occupied and unoccupied trips made by self-employed drivers are essential for optimized vehicle dispatch by ride-hailing services (e.g., Didi Dache, Uber, Lyft, Grab, etc.). However, the occupancy status of vehicles is not always known to the service operators due to adoption of multiple ride-hailing apps. In this paper, we propose a novel framework, Learning to INfer Trips (LINT), to infer occupancy of car trips by exploring characteristics of observed occupied trips. Two main research steps, stop point classification and structural segmentation, are included in LINT. In the stop point classification step, we represent a vehicle trajectory …

Barriers To “New Mobility”: A Community-Informed Approach To Smart Cities Technology, Aaron Golub, Vivian Satterfield

PSU Transportation Seminars

There is an active debate about the potential costs and benefits of emerging “smart mobility” systems, especially in how they will serve communities already facing transportation challenges. This presentation will describe the results of an assessment of these equity impacts in the context of lower-income areas of Portland, Oregon, based on a mixture of quantitative and qualitative research.

Portland, Oregon’s proposal for the U.S. Department of Transportation’s Smart City Challenge, “Ubiquitous Mobility for Portland,” focuses on developing mobility solutions that would serve traditionally underserved populations (low-income, communities of color, and residents with mobility challenges). This study found that by lowering …

Data From: Market Segment Prediction Tool, Philip L. Winters, Amy Lester

TREC Datasets and Databases

Social marketing seeks to develop and integrate marketing concepts with other approaches to influence behaviors that benefit individuals and communities for the greater social good. Social marketing is a useful transportation demand management (TDM) planning approach to promote travel-behavior change, and combines at least seven distinguishing features that sets it apart from other popular, behavior-change planning approaches, such as education and mass media campaigns. These seven features include a focus on socially beneficial behavior change; a strong consumer orientation; the use of audience segmentation techniques and the selection of target audiences; the use of marketing’s conceptual framework (marketing mix and …
